That rare event where tried and true Debian releases a new version. "This new version of Debian includes various interesting features such as multiarch support, several specific tools to deploy private clouds, an improved installer, and a complete set of multimedia codecs and front-ends which remove the need for third-party repositories. Multiarch support, one of the main release goals for 'Wheezy', will allow Debian users to install packages from multiple architectures on the same machine. This means that you can now, for the first time, install both 32- and 64-bit software on the same machine and have all the relevant dependencies correctly resolved, automatically."

Unless you're getting something really barebones that's been on the store shelves a while, you're probably going to need newer kernel, xorg, lm-sensors, Nividia/Ati drivers and some other libs from a more recent branch to play nice with brand new hardware, I'd wager.

Then again, I don't run Stable (or even Debian anymore), so what do I know.

I run Stable, I like stable, a 3.2 kernel will be new enough, and I can eventually update what I want from Backports, when things become available. My current rig runs squeeze, with some software from backports, it's amazingly stable, and fast.

ATI and NVidia drivers are in non-free, so there is no issue there, Virtualbox from oracle, and xfce 4.10, and I'm good.
